It depends on how close you think that horizon might be. That specific camera is of course a professional one, and I imagine the price will reflect this -- and put it above the reach of most of us here. It is unlikely that its footage will be edited by the likes of Video Studio.

However, I accept that as Canon and other manufacturers launch professional-end HEVC cameras, they will undoubtedly be working on expanding the range and lowering the cost to the point that you and I will start buying them. But I don't expect that to happen for another couple of years. Where companies like Corel will be in this inevitable race is, however, far less easy to predict... And don't forget the requirement for high-end computer chips to be able to process HEVC.

I shoot enough 4K and while a smaller file size to work with is nice, I can imagine what computer specs you will need to be able to work with it. But that's way down the line.Samsung's NX1 was way ahead of it's time using that H265 as it's only codec. Nothing could edit it natively with lots of transcoding going on. Since most of my 4K videos are under 10 minutes, Panasonic's MP4 is working just fine.
